Abstract
Description
Technical Field
[0001] This application belongs to the field of cable laying technology, specifically relating to a system and method for automatically generating cable laying paths. Background Technology
[0002] With societal development, the scope of electricity use continues to expand. As a result, the number of cables used in power transmission processes is constantly increasing, and users' requirements for cable installation methods are also continuously rising.
[0003] In related technologies, the main method of cable laying is for workers to lay cables based on their experience or the shortest path, according to the starting and ending points of the laying process. However, laying cables based on experience is prone to subjectivity, and the optimal laying locations for different cables are not entirely the same. Furthermore, at the same location, different cables experience varying degrees of external environmental influence, or have different impacts on the external environment. Therefore, using existing technologies for cable laying results in incomplete data, leading to inaccurate laying results and unreasonable laying methods. Summary of the Invention

[0048] The system and method for automatically generating cable laying paths provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.
[0049] Example 1
[0050] Figure 1 This is a flowchart illustrating the method for automatically generating cable routing paths provided in Embodiment 1 of this application. Figure 1 As shown, the specific steps include the following:
[0051] S101, Obtain a region map of the area where the cable to be laid is to be obtained, and determine the starting point and ending point of the cable laying based on the region map.
[0052] First, this solution can be used in scenarios involving cable routing planning, especially in scenarios involving cable routing planning within a certain area.
[0053] Based on the above usage scenarios, it is understandable that the main body executing this solution can be a smart terminal with image recognition, data processing and path drawing functions, such as mobile phones, tablets and desktop computers, etc., without further restrictions.
[0054] The cable to be laid can be a cable used for signal and power transmission within a designated area. The area map can be a map of the area where the cable to be laid will be located. The area map includes parameters of existing above-ground and underground buildings, pedestrian traffic, and existing power facilities in the area, as well as pre-set start and end point locations for the cable to be laid by the user. The parameters of the existing power facilities include current, voltage, electromagnetic wave intensity, location, and structural parameters. The start point location can be the actual geographical location of the cable's starting point within the area. The end point location can be the actual geographical location of the cable's ending point within the area. Both the start and end points can be represented by latitude and longitude parameters.
[0055] In one embodiment, a region map of the cable to be laid, uploaded by the user or pre-stored, can be obtained through a data transmission interface. The starting point and ending point of the cable to be laid in the region map can be identified. The starting point and ending point of the cable to be laid can be calculated based on the coordinates of the location identifiers in the region map and the conversion relationship between the coordinates of the region map and latitude and longitude.
[0056] S102, read the cable parameters of the cable to be laid, and determine the laying parameters of the cable to be laid based on the cable parameters; the laying parameters of the cable to be laid include: laying position parameters and laying structure parameters.
[0057] The cable parameters to be laid include the cable's intrinsic parameters, such as its shape, model, material, size, and function; and its transmission parameters, such as current, voltage, electromagnetic wave intensity, and resistance. The laying parameters can be the laying requirements determined according to cable laying construction specifications and the cable parameters, such as the laying method, laying level, laying structure, and laying location. The laying method includes above-ground and underground laying. The laying structure includes horizontal and vertical laying. The laying level includes the level at which the cable is located in a vertical laying structure. When cables are laid on a multi-layered support structure in a vertical structure, they are arranged from top to bottom according to voltage, with high-voltage cables in the first layer, followed by low-voltage power cables, control cables below the power cables, and instrument cables at the bottom. When low-voltage power cables and instrument cables are laid on the same layer, they should be separated by a partition. The laying location includes locations that the cable should avoid and the optimal laying location. For example, the pressure on the cable to be laid at the laying location should be less than the maximum pressure it can withstand, and the cable should not be laid in direct sunlight or in locations with extremely high temperatures.
[0058] In one embodiment, the cable parameters of the cable to be laid can be read from a pre-stored cable parameter correspondence table based on the name of the cable to be laid. Alternatively, the laying parameters can be read by scanning the identification mark of the cable to be laid, such as a QR code. The optimal laying method and the laying threshold for safe operation of the cable to be laid are determined based on the cable parameters, cable laying construction specifications, and power engineering cable design standards. The laying parameters of the cable to be laid are then determined based on the optimal laying method and the laying threshold. For example, when laying cables horizontally, they should be laid in a single layer without crossings. Bends should be based on the allowable bending radius of the cable with the largest cross-section. Cables of different voltage levels should be laid in layers, with high-voltage cables laid on the upper layer. When cables of the same voltage level are laid along supports, the horizontal clearance should not be less than 35mm. The laying threshold includes the maximum pressure threshold, the highest temperature threshold, and the maximum operating voltage threshold that the cable to be laid can withstand. The laying parameters of the cable to be laid include laying location parameters and laying structure parameters.
[0059] S103, generate at least two candidate deployment paths for the cable to be deployed based on the deployment start point location, the deployment end point location, the deployment location parameters, and the deployment structure parameters.
[0060] The candidate deployment path can be any path among at least two possible deployment paths of the cable to be deployed that meets at least one of the following conditions: lowest deployment cost, lowest construction difficulty, and lowest probability of impact. The cable to be deployed can be safely and stably deployed along the candidate deployment path for power and data transmission. The possible deployment paths can be at least two paths obtained by connecting the deployment start point, the deployment end point, and the deployable location. The deployable location can be a location that meets the deployment location parameters.
[0061] In one embodiment, the remaining deployment locations in the area map can be determined based on the parameters of the existing power facilities in the area. The feasible deployment locations of the cable to be deployed within these remaining locations can be determined based on the parameters of above-ground and underground buildings, pedestrian traffic, the deployment location parameters, and the deployment structure parameters in the area map. At least two feasible deployment paths for the cable to be deployed are generated by connecting the deployment start point, the deployment end point, and the feasible deployment locations. One of the following conditions—deployment cost, construction difficulty level, and impact probability—is calculated for each feasible deployment path. The calculation results are sorted in ascending order, and the top two feasible deployment paths are identified as candidate deployment paths. Alternatively, corresponding weights can be assigned to deployment cost, construction difficulty level, and impact probability, and a weighted sum of the deployment results for each feasible deployment path can be calculated. The calculation results are then sorted in ascending order, and the top two feasible deployment paths are identified as candidate deployment paths.
[0062] In one feasible embodiment, optionally, before generating at least two candidate deployment paths for the cable to be deployed based on the deployment start point location, the deployment end point location, the deployment location parameters, and the deployment structure parameters, the method further includes:
[0063] The intermediate position between the deployment start position and the deployment end position is determined based on the deployment position parameters.
[0064] At least two connection paths are generated by connecting the starting point, the intermediate point, and the ending point of the deployment.
[0065] Read the regional parameters in the regional map, and determine at least two deployable paths in the connection path based on the regional parameters and the layout structure parameters; the regional parameters include the above-ground structure parameters and underground structure parameters at each location in the regional map.
[0066] The intermediate location for cable laying can be any possible location between the starting and ending points of the cable laying process. Regional parameters can include existing above-ground and underground building parameters, pedestrian traffic parameters, and parameters of existing power facilities in the region as shown in the regional map. The power facility parameters include the structural parameters and location parameters of above-ground and underground power facilities. The regional parameters include the above-ground and underground structural parameters at various locations on the regional map.
[0067] In one embodiment, the intermediate location of the cable to be laid between the starting point and the ending point can be determined based on the deployment location parameters. Connecting the starting point, the intermediate location, and the ending point generates at least two connection paths. By scanning barcodes or using image recognition on the area map, the area parameters in the area map are read. Based on the area parameters and the deployment structure parameters, deployment structure parameters and deployment location parameters that conflict with existing above-ground and underground building parameters, pedestrian flow parameters, and already deployed power facility parameters in the area map are determined. Connection paths passing through conflicting locations and / or conflicting structures are filtered out, resulting in two deployable paths.
[0068] This solution generates connection paths based on the location parameters of the cable to be laid, and then filters out layable paths based on the area parameters in the area map. This achieves the goal of automatically generating layup paths by combining the cable's own parameters and the external layup area parameters, increasing the comprehensiveness of the basis for generating cable path layouts and thus improving the accuracy of the generated cable path layouts.
[0069] In one feasible embodiment, optionally, generating at least two candidate deployment paths for the cable to be deployed based on the deployment start point location, the deployment end point location, the deployment location parameters, and the deployment structure parameters includes:
[0070] Read the region parameters of the intermediate location of the deployment in the region map, and calculate the influence probability of the cable to be deployed at the intermediate location of the deployment based on the region parameters; the influence probability includes: the influence probability of the cable to be deployed on the deployment area and the influence probability of the deployment area on the cable to be deployed;
[0071] Calculate the influence probability of the cable to be laid in each possible laying path based on the influence probability of the cable at the intermediate position of the laying;
[0072] The two deployable paths with the lowest probability values are selected as candidate deployment paths.
[0073] The probability of the cable to be laid affecting the installation area at the intermediate location of the installation includes: the probability of the cable to be laid affecting the installation area and the probability of the installation area affecting the cable to be laid. The probability of the cable to be laid affecting the installation area includes: the probability of the electromagnetic waves from the cable to be laid affecting the lives of surrounding residents, the probability of the electromagnetic waves from already installed cables affecting surrounding construction, etc. The probability of the installation area affecting the cable to be laid includes: the probability of the cable to be laid being subjected to mechanical external forces, the probability of overheating, the probability of potential construction in the surrounding area, the probability of electromagnetic wave influence from existing external cables, and the probability of external pressure exceeding the maximum withstand pressure of the cable to be laid, etc.
[0074] In one embodiment, the regional parameters of the intermediate deployment location in the regional map are read. Based on the regional parameters, the distribution of pedestrian traffic, above-ground and underground buildings, and the existing cable deployment status in the regional map are determined. The probability of each influencing factor on the cable to be deployed at each intermediate deployment location is calculated based on the pedestrian traffic, above-ground and underground building distribution, existing cable deployment status, and cable parameters such as current, voltage, model, and material of the cable to be deployed. For example, the electromagnetic wave intensity emitted by the existing cable at the intermediate deployment location is determined based on the existing cable deployment status. The ratio of this electromagnetic wave intensity to the maximum electromagnetic wave intensity that the cable to be deployed can withstand under stable operation is calculated, and this ratio is used as the probability of electromagnetic wave influence from the existing cable. The sum of the probability of influence of all influencing factors at each intermediate deployment location is used as the probability of influence at each intermediate deployment location. The sum of the probability of influence of all intermediate deployment locations for each deployable path is calculated, and the two deployable paths with the smallest sum of probability of influence are selected as candidate deployment paths.
[0075] This scheme calculates the impact probability of the cable to be laid in each possible laying path and determines the laying path with the lowest impact probability as the candidate laying path. It can comprehensively consider the impact of the cable itself on the external environment and the impact of the external environment on the cable operation during the cable laying path planning process, thereby improving the rationality of the cable laying path planning.
[0076] In one feasible embodiment, optionally, generating at least two candidate deployment paths for the cable to be deployed based on the deployment start point location, the deployment end point location, the deployment location parameters, and the deployment structure parameters includes:
[0077] Read the regional parameters of the intermediate location of the deployment in the regional map, and determine the construction difficulty level of the intermediate location of the deployment in the regional map based on the regional parameters;
[0078] Calculate the construction difficulty level of each deployable path in the area map based on the construction difficulty level of the intermediate location of the layout in the area map;
[0079] The two possible paths with the lowest construction difficulty level are selected as candidate paths.
[0080] The construction difficulty level can be determined based on the actual terrain conditions of the feasible path, the number of buildings to be bypassed, and construction safety. It is understood that the more complex the actual terrain conditions of the feasible path, such as the more ravines, the more winding the terrain, and the greater the elevation difference, the higher the construction difficulty level. The more buildings the feasible path needs to bypass, the higher the construction difficulty level; the more hazardous factors during construction, such as working height, the possibility of electric shock, and the possibility of mechanical injury, the higher the construction difficulty level.
[0081] In one embodiment, regional parameters of the intermediate locations in the area map can be read. Based on these parameters, the terrain conditions, building distribution, and factors affecting construction at each intermediate location can be determined. These factors are then graded according to preset rules, and the sum of these grades is used as the construction difficulty level of each intermediate location in the area map. The preset rules can be implemented by comparing the terrain conditions, building distribution, and factors affecting construction at each intermediate location with existing cable deployment big data. Locations with higher grades than existing cable deployment big data are assigned a level two score, while those with lower or equal grades are assigned a level one score. The existing cable deployment big data can be a database of successfully deployed cables corresponding to the model and function of the cable to be deployed. The sum of the construction difficulty levels of all intermediate locations along each deployable path in the area map is calculated, and at least the two deployable paths with the lowest sum of construction difficulty levels are selected as candidate deployment paths.
[0082] This solution calculates the construction difficulty level of each possible cable laying path and selects the few paths with the lowest construction difficulty level as candidate laying paths. This allows for a comprehensive consideration of the success rate of cable construction during the cable laying path planning process, further improving the rationality and accuracy of cable path planning.
[0083] S104, obtain the environmental parameters of the at least two candidate deployment paths, and determine the final deployment path of the cable to be deployed based on the preset weight of each environmental factor and the environmental parameters corresponding to each environmental factor.
[0084] The environmental parameters of the candidate deployment path can be parameters related to the natural environmental influences on the cable to be deployed along the candidate deployment path. Environmental factors can be natural environmental influences on the cable to be deployed along the candidate deployment path, including temperature, humidity, corrosivity, and natural disasters. The temperature environmental parameter is the difference between the actual temperature of the external environment and the optimal temperature for the cable deployment environment; the humidity environmental parameter is the difference between the actual humidity of the external environment and the optimal humidity for the cable deployment environment; the corrosivity environmental parameter is the probability that the external environment can corrode the insulation material of the cable to be deployed; and the natural disaster environmental parameter is the frequency of natural disasters occurring in the external environment.
[0085] In one embodiment, environmental parameters of the at least two candidate deployment paths can be obtained by uploading environmental data from sensors pre-installed at the deployment location. Alternatively, environmental parameters can be obtained by reading historical natural disaster data from the deployment locations traversed by the candidate deployment paths. Based on preset weights for each environmental factor and the corresponding environmental parameters, a weighted sum of environmental parameters for each candidate deployment path is calculated. The candidate deployment path with the smallest weighted sum of environmental parameters is determined as the final deployment path for the cable to be deployed.
[0086] In one feasible embodiment, optionally, obtaining the environmental parameters of the at least two candidate deployment paths and determining the final deployment path of the cable to be deployed based on the preset weights of each environmental factor and the environmental parameters corresponding to each environmental factor includes:
[0087] Obtain historical natural disaster data for the at least two candidate deployment paths;
[0088] Based on the preset weights of each environmental factor and the historical natural disaster data corresponding to each environmental factor, the environmental weighting value of the candidate deployment path is calculated, and the candidate path with the smallest environmental weighting value is determined as the final deployment path of the cable to be deployed.
[0089] Historical natural disaster data may include the frequency of fires, floods, and earthquakes that have occurred in or around the candidate deployment path. The preset weights for each environmental factor may be weights pre-assigned to each environmental factor based on its influence on the deployment path.
[0090] In one embodiment, historical natural disaster data of the at least two candidate deployment paths can be obtained by reading historical natural disaster data records within the area map. Based on the preset weights of each environmental factor and the historical natural disaster data corresponding to each environmental factor, the environmental weighted sum of the candidate deployment paths is calculated, and the candidate path with the smallest environmental weighted sum is determined as the final deployment path of the cable to be deployed.
[0091] This scheme, by combining historical natural disaster data to determine the final cable laying path, can achieve the goal of planning cable laying paths in conjunction with external environmental factors, thereby improving the safety of cable laying and extending the service life of cables.
[0092] The technical solution provided in this application embodiment obtains a region map of the area where a cable is to be laid, and determines the starting and ending positions of the cable to be laid based on the region map; reads the cable parameters of the cable to be laid, and determines the laying parameters of the cable to be laid based on the cable parameters; the laying parameters of the cable to be laid include: laying position parameters and laying structure parameters; generates at least two candidate laying paths for the cable to be laid based on the laying starting position, the laying ending position, the laying position parameters, and the laying structure parameters; obtains the environmental parameters of the at least two candidate laying paths, and determines the final laying path of the cable to be laid based on the preset weights of each environmental factor and the environmental parameters corresponding to each environmental factor. The above-described method for automatically generating cable routing paths solves the problems of insufficient routing basis, inaccurate routing results, and unreasonable routing methods when using existing technologies for cable routing. By reading the cable parameters of the cable to be routed, the routing parameters of the cable to be routed are determined. Based on the starting position, ending position, and routing parameters, at least two candidate routing paths for the cable to be routed are generated. The final routing path of the cable to be routed is determined by weighting and summing the environmental factors of each candidate routing path. This achieves the goal of automatically generating cable routing paths by combining internal and external factors of the cable, improving the rationality of the cable routing method and the accuracy of the routing results.
[0093] Example 2
[0094] Figure 2 This is a flowchart illustrating the system for automatically generating cable routing paths provided in Embodiment 2 of this application. Figure 2 As shown, the specific steps include the following:
[0095] S201, Obtain a region map of the area where the cable to be laid is to be obtained, and determine the starting point and ending point of the cable laying based on the region map.
[0096] S202, read the minimum bending radius of the cable to be laid, and determine the laying parameters of the cable to be laid according to the minimum bending radius of the cable and the preset cable laying rules.
[0097] The minimum bending radius of the cable can be defined as the limit of the bending radius that the cable to be laid can withstand during manufacturing, transportation, and installation. The minimum bending radius is related to the material and structural characteristics of the cable. The cable conductor is composed of multiple single-core wires twisted together at a certain pitch. During conductor manufacturing, the number of single wires and the pitch determine the stability of the conductor during bending. Excessive bending will lead to loosening and bulging of the conductor, directly affecting the performance of the outer semiconducting layer and insulation layer. For example, when the cable is bent at a certain bending radius, the insulation at the bend will undergo tensile deformation. When the bending exceeds the minimum allowable bending radius, it may cause insulation damage.
[0098] In one embodiment, the minimum bending radius of the cable corresponding to the cable to be laid is read from the minimum permissible bending radius table based on the cable type. The minimum permissible bending radius table is as follows:
[0099]
[0100] The range of the next laying position that the cable to be laid can reach from the previous laying position is determined based on the minimum bending radius of the cable. The laying parameters that the cable to be laid can reach within the range of the next laying position are determined according to the cable's voltage, model, and function, following a preset cable laying rule. The preset cable laying rule can be at least one of cable laying construction specifications and power engineering cable design standards, and is an existing cable laying specification or standard, which will not be elaborated here.
[0101] In one feasible embodiment, optionally, determining the laying parameters of the cable to be laid based on the minimum bending radius of the cable and preset cable laying rules includes:
[0102] The laying range of the next possible laying position of the cable is determined based on the starting position of the cable to be laid and the minimum bending radius of the cable.
[0103] The next laying position parameters of the cable to be laid within the laying range are selected according to the preset cable laying rules.
[0104] Read the cable model of the cable to be laid, and determine the laying structure parameters of the cable to be laid based on the cable model, the next laying location parameters, and the preset cable laying rules.
[0105] The deployment range of the next deployable location can be the range of the next deployment location that the cable to be deployed can reach from the deployment starting point position according to the minimum bending radius of the cable.
[0106] In one embodiment, one end of the cable to be laid can be fixed according to the starting position of the cable laying. The cable can then be rotated with one end fixed, according to the minimum bending radius of the cable. The fan-shaped area scanned by the rotated cable is determined as the laying range of the next possible laying position. The next laying position parameters of the cable within the laying range are filtered according to the preset cable laying rules, cable length, and area parameters of the area map. The cable model of the cable to be laid is read, and the laying structure parameters of the cable are determined according to the cable model, the next laying position parameters, and the preset cable laying rules.
[0107] This solution determines the next possible location of the cable based on the starting point of the cable and the minimum bending radius of the cable. Then, it determines the location parameters and structural parameters of the cable based on preset cable laying rules. This allows for the generation of cable laying paths without damaging the cable, thus improving the reliability of the cable laying path planning results.
[0108] S203, generate at least two candidate deployment paths for the cable to be deployed based on the deployment start point location, the deployment end point location, the deployment location parameters, and the deployment structure parameters.
[0109] S204, obtain the environmental parameters of the at least two candidate deployment paths, and determine the final deployment path of the cable to be deployed based on the preset weights of each environmental factor and the environmental parameters corresponding to each environmental factor.
[0110] The technical solution provided in this application embodiment reads the minimum bending radius of the cable to be laid, and determines the laying parameters of the cable to be laid based on the minimum bending radius and preset cable laying rules. This avoids the problem of cable damage caused by excessive bending during cable laying and improves the reliability of obtaining cable laying parameters.
